Dulu pear tree is the most common tree on the grave, and it has become the first choice of trees in front of the grave together with conifers and willows. Pear trees are planted in graves and have a long history. Today, the long-growing Dulu pear tree can still be seen in some graves, and it is still in full bloom and full of fruits every year.
The reason why Du Lishu became a tree in front of the grave is because the homonym of Du Lishu is called "abdominal separation". Planting pear trees in Dulu indicates that the deceased can be reborn as soon as possible and leave the mother's womb as soon as possible. So Du Lishu became a grave robbing tree. Both the pear tree and the pear tree have bad meanings, and they are not planted at home.
As the saying goes, today's locust tree is not an ordinary locust tree. Just from the name, Sophora japonica was introduced from abroad, also called Robinia pseudoacacia. Planting was introduced only in the late Qing Dynasty, so the planting history is relatively short. As the saying goes, Sophora japonica refers to the traditional tree species in China: Sophora japonica.
